The blade bolt head on a 21" trim mower has been stripped for a couple months. Fixing it has been put off because I am not sure what else to do in an attempt to loosen it. The bolt head is mis- shaped and can not be wrenched. Hopefully some one might have some ideas on how this can be solved. By the way if any one ever should does a search to check on cubcadet push mowers this is one and I am sincere that I hold it dear! Bought it at Lowe's Hardware Had it since Spring. Blade bolt is my own fault I guess? Thank You for your future help!
